The demand for housing in Canada is on the rise, necessitating solutions that not only address affordability and cost concerns but also align with climate-change objectives, prioritize energy efficiency, reduce carbon emissions, promote social acceptance, and enhance resilience. Recognizing the construction sector's significant impact on the environment through the consumption of natural resources, energy use, and construction waste production, the study emphasizes the importance of sustainable building material parameters and the method of selection. Typically, building material selection focuses primarily on cost, potentially neglecting other critical sustainability factors, thus compromising residential performance and consumer living standards. An alternative approach, the eco-design method, offers a more flexible strategy by assessing multiple equitable parameters such as environmental impacts, affordability, social acceptance, material availability, and technological expertise. In contrast to conventional ad-hoc selection practices, the integration of Multi-Criteria Decision Making (MCDM) with a flexibility to change the parameter weightage based on stakeholder perception emerges as a pivotal method for selecting sustainable building materials. This approach addresses challenges and provides a systematic approach to prioritizing materials based on various selection criteria, considering different stakeholder/user inputs. Developing the framework for evaluating construction materials and methods based on sustainability parameters offers a flexible and user-friendly tool that allows stakeholders to dynamically adjust weights assigned to various criteria to obtain the most resilient materials and systems for a range of potential variations. By enabling iterative weight adjustments and scenario analysis, this framework aims to assist stakeholders in making well-informed decisions that optimize performance while minimizing environmental impact, thereby promoting the adoption of more sustainable construction practices. This tool offers a significant opportunity for local practitioners, policymakers, and homeowners to assess materials and systems through various equitable perspectives. It allows them to choose the optimal material combination tailored to specific residences, considering the users’ perspectives.

摘要

The demand for housing in Canada is on the rise, necessitating solutions that not only address affordability and cost concerns but also align with climate-change objectives, prioritize energy efficiency, reduce carbon emissions, promote social acceptance, and enhance resilience. Recognizing the construction sector's significant impact on the environment through the consumption of natural resources, energy use, and construction waste production, the study emphasizes the importance of sustainable building material parameters and the method of selection. Typically, building material selection focuses primarily on cost, potentially neglecting other critical sustainability factors, thus compromising residential performance and consumer living standards. An alternative approach, the eco-design method, offers a more flexible strategy by assessing multiple equitable parameters such as environmental impacts, affordability, social acceptance, material availability, and technological expertise. In contrast to conventional ad-hoc selection practices, the integration of Multi-Criteria Decision Making (MCDM) with a flexibility to change the parameter weightage based on stakeholder perception emerges as a pivotal method for selecting sustainable building materials. This approach addresses challenges and provides a systematic approach to prioritizing materials based on various selection criteria, considering different stakeholder/user inputs. Developing the framework for evaluating construction materials and methods based on sustainability parameters offers a flexible and user-friendly tool that allows stakeholders to dynamically adjust weights assigned to various criteria to obtain the most resilient materials and systems for a range of potential variations. By enabling iterative weight adjustments and scenario analysis, this framework aims to assist stakeholders in making well-informed decisions that optimize performance while minimizing environmental impact, thereby promoting the adoption of more sustainable construction practices. This tool offers a significant opportunity for local practitioners, policymakers, and homeowners to assess materials and systems through various equitable perspectives.
